View 1 Repliesafter my last post i dove into remoting to try to solve my performance problem in a client-server fashion.
This works very well, but i come across a big problem which i don't seem to get solved.
I made a well known singleton servicetype on the server that retrieve all customers. Whith 1 db connection this works fine. But very often customers and i use in 1 sql instance multiple databases (for each administration a separate db). so the whole purpose of a singleton object is hereby destroys as soon i connect in my class to a different db. Is there some way to overcome this for example threading or running multiple servers (for each db it's own server-application)?
I don't really know how to code but am pretty good at tweaking. I'm trying to set up a script that I can run to delete a single file, multiple files, a folder or multiple folders on a list of servers.I was thinking that the script could read the files to be deleted from a .txt file and apply the deletion to a list of servers in another .txt file.Example:
FilesToBeDeleted.txt:
\(insert_server_name_from_list)c$Program FilesBINexample_file.rpt

if for example i have two private sub I declared a local variable on private sub a... is there a way that private sub b could use the variable created on private sub a? Im asking because im in a problem in my app were using global variable is not an option to make the long story short
View 5 RepliesI always used to define variables like Dim xxxx As yyyyy. In the tutorials I'm looking at though they do Private Const xxxxx As yyyyy. I wonder just what is the difference here? What is the significance of this change? What am I actually doing with 'Dim' and what is this Private Const doing different?
View 12 RepliesIn the following code as you see I am defining myFile inside the timer sub; which of course is not a good idea. The FilePath is derived in form load before the timer kicks in. How can I declare myFile globally so it can be used in timer sub as well as in form load?
Private Sub tmrInterval_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrInterval.Tick
Dim myFile As New IO.FileInfo(FilePath)
If myFile.Exists Then
...
...
I want something like this:
Public Class Form1
private myFile As New IO.FileInfo()
'but I do not have strMessageFilePath value yet, that will be achieved in form load.
In Vb6 you could make a private type by doing the following:
Private Type PointAPI
X As Integer
y As Integer
End Type
Vb.Net doesn't support this. I need it to store the x and y position of a certain pixel. I know i could just declare an x and y variable but i would rather use something like:
xyCentre.X = 5
xyCentre.Y = 10
I am completely lost on procedures. Whats the difference bewteen Private sub and private function?
View 1 RepliesI'm using the details on connecting to a server from a client here: [URL]
It's quite out dated but I just need it for a quick project. I need the client to auto-connect. This program will be running on the LAN only, is there a way to find on what computer the server is running on (i.e. all computers hosting the specific server on port x). I've seen it on a couple of games that run on LAN. Without access to the internet, they manage to display all available games on the local LAN. I'm doing this with VB.net.
I am using the following code to get the Disk I/O on various servers. For now I am just retrieving the DiskReadsPerSec to get a feel for it. The return data gives a uint32 for each drive on the server and a total. My questions is what is the time frame that this represents? Is this at the second that my code polls the drive or is this over the last few seconds or do I need to do multiple runs to get an average.
My intention is to build a graph for each drive so I wonder how often I need to poll the drive to get a acurate value.
Public Shared Function GetDriveIO(ByVal strip As String) As Boolean
Dim oConn As New ConnectionOptions()
Dim lnglist As New List(Of Long)

I have developed a program with vb2010, created an installer with installaware and installed the program on my develop laptop and on my normal desktop pc (both win 7 64bits, but program runs on 32 bits).So on my laptop it run perfectly, but when I try to run it on my desktop pc, the only thing I see is the admin message (the program needs admin rights) and than nothing happends (even checked the taskmanager, it shows the program for a short while and closes it even as fast as it opens).I don't know what went wrong, the installer checks the framework which is needed (4.0), but I have that already installed on my desktop pc.

View 6 Repliesim v ery new to VB, im designing a game launcher within VB and everything is very simply done. I have 4 buttons currently, 3 of them link to websites and work a charm, but what i need is a 4th button to launch a game via a .cmd file. I tried by using simple commands like:
Shell("C:Program Files (x86)NCsoftAtomixatomix.cmd")and Process.Start("C:Program Files (x86)NCsoftAtomixatomix.cmd")
Both of these options worked in executing the .cmd but it caused an error within it. The cmd works perfectly fine when executed manually from its directory but when i try and execute it via the launcher i get an error.

View 3 RepliesA little background, the client that I am working with has an enterprise AD that is a mess. They have no containers for servers or any organization what-so-ever. They also shutdown servers and did not remove them properly from AD. So I needed to come up with a program that would find all the windows server, identify them by OS, and then check to see if they would actually respond to a ping. (I am aware that this is not a perfect method if they are refusing ICMP's but its good enough for my purposes). The completion of the program will display all the information and then allow the user to save the excel workbook in a location that they choose.

View 2 RepliesThe title of this thread perhaps does not explain my problem correctly.Actually i am developing a financial software for a company.The software is similar to a banking system. The software is being developed using VB 2008 and SQL Server 2008.The company has its branches located at different locations. They are having a centralized SQL Server at their Head Office.The branches are connected to Head Office using a VPN.Now what we are worried about is when the VPN gets disconnected.For that we will be having a SQL server installed at each of the branches.When VPN is connected the the details entered will be directly at the Head Office database,Meanwhile a program will be executed which will get details from the Head Office database at each of the branches in a XML file.When a branch gets disconnected from the VPN another program will get the XML details into the Sql Server installed at the branch. When the branch is connected again Another application will create a xml file from the local server and insert its details into the HO server.The sizes of the XML are reaching upto around 150 to 200 mb. I am using Dataset.WriteXML and Dataset.ReadXMl. I have tested this on my local machine it is taking upto 30-40 secs.I dont know how much it will take when the actual application is installed. How can i speed things up ? Does anyone have any idea on how i can do the whole process more smoothly and faster?

Now what I need to know is, if a user has proxy settings configured in IE, will this code automatically use the proxy?Also what happens when said proxy needs authentication?Anyone know how this can be adapted. I know about the System.Net.WebProxy class, however I would really need this to pick up the settings from IE by default and then if required (and only if required) pop up for proxy authentication.

Basically what I have are two loops, one inside the other, that will run until the given condition is met. Exactly what I want. My problem is that I want to be able to use the controls, like buttons, while a loop is going on.
I originally did not think of this until I had built this part of my program, what I want to know is if there is a way to use controls while a loop is going on or if their is an alternative.
1)I know timers can be used to meet these goals, but they did not work out as I had hoped and using two timers (1 to represent each loop) I do not believe is efficient.
2)I have considered using recursion, but have found this may not be very efficient either and am not quite sure if this will do what I want.
These loops run as long as the number the user inputted. So it could theoretically run for 100,000+ times. I am not looking for speed, but it would be good if there were a faster method that allowed me to use controls while it loops.
I need my program to check if a program is running. The program i'm talking about is Need For Speed World. (NFSW).If the program is running then, I want Label1 to say "Running". And if not: "Not Running".
